CARPET- CLEANING AJZPA BATUS.

Tool! whomzt may concern:

lie it known that I, MA'rrHEw G. WAR- xocn, a citizen of the State of California, have inventednew and useful Improvements in Carpet-Cleaning Apparatus, of which the following is a,

specification.

This invention relates to improvements in rarpet cleaners and more particularly to the plurality of heaters or kind provided-with a raise the dirt and dust and deliver the; same to a bag or receptacle. One object of the invention is the provision of a portable cleaner provided with-a plurality of rotatable disks and a plurality kagit-ators yieldingly connected to-said S s Another object is the provision of-a 'port i fan and-1' ;outwardly' unt1l the opposite or front side able cleaner provided with a suction a casin having a tapered duct through which t 1e dust is drawn by the fan.

With these will more fully hereinafter appear the present invention consists in certain novel details of construction and parts hereinafter to be more illustrated in the accompanying drawings and more particularly pointed out in the appended claims, it being understood that various changes in the form, proportion, size and minor details of the device may be made within the scope .of the appended claim, without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings-forming apart of the specification :I"igure 1 is a rear view of the device showing the handles in section. Fig. 2 is an end view of the same. Fig. 3 is'a transverse sectional view on the line 3-3 of Fig. 1. Fig. 4 is a detail 'side arrangement of elevation of the agitator disk with a portion adjacent its periphery broken away and showing the agitator in side elevation and the means for securing the agitator to the disk. Fig. 5 is a section'al planyiewofonc end of the sectionalpliiin view of the rear port-ion of the casing. 1' Similar numerals of rcfertince are ployed to designate throughout. v v A platform is designated bythe numeral corresponding parts Specification 0': Letters Patent.- Application and-Januar 's, 1910, semi No. 537,067.

The armature shaft. '12 of the motor extends through the fan casing and is provided with a suction fanof any -well known type.

What will subsequently be termed a main casing is-designated in general by the numeral-13. "This f of: its opposite ends, [piece-pf sheet metal. .mg, the portion adjacent one of its-longitucasing, with the exception is formed of a single In forming the casdlnal'sides is curved in the direction of its length, this curvature formingthe rear side 14 of the casing. The metal is then curved 15.0f the casing has its edge in a plane with and spaced from the edge of the opposite side 14, as clearly shown in Fig. 3. Each end of the casing is closed by an end Wall opposite sides of the platform.

The casing is fixedly secured to the center of the fan casing 11 byme'ans of a pair of brackets 17 and 18 and formed in the middle 14 is an opening surrounded by a neck 19 which enters a central opening formed thefront side of the fan casin 11.-

By reference now to Fig. 6, it will be seen portion of the rear Wall 14: is centrally provided with an opening, and extending longitudinally of the Wall 14: are channels 20, the said channels being formed by bulging the wall outwardly along its longitudinal central line,'the said channels decreasing in depth as the oppositoends of the rear wall are approached.

By reference now to Fig. 5, it will be seen that the casing is interiorly provided with a plurality of spaced partitions 2l'c0nforming to the fixedly secured in any preferred manner within the, casing.

reference now to Figs; 1 to Elinclusive, v ll be seen that lapped inio the upper e of the an casing 11 is one end of an outlet pipe 37. The outlet pipe 37 is curved so and. errcnds forwardly from the casing 11 3; will be imparted em loyed Withoutdeparting from the ens, 232 v and arranged on its free end is a bug or other suitable receptacle 38 which is supported by the upper side of the casing 13.

Having now described the construction of the device its operation Wlll be given-:

It will be evident when the motor is in operution and the lower open side of the casing placed over a piece of carpet or other motcriel to be cleaned that the rotary movement of the agitators will misc flue-dust. It Will be observed, owing to the partial vacuum created by the fan that the particles of dust will follow the direction of the arrows shownin Fig. 8 and enter the duct formed by the inclined grooves 21 and recesses and finally pass into the fan casing tl'lrough the neck 19, after which they will be driven through the outlet pipe 3'? and into the bug or receptacle 38.

It will be observed by reference to Fi s: 1 to 3 inclusive the; on end walls 16 or the casing are provi ed,- edieeent their forward ends with a pair of rollers 40 and ll. rollers are carried by bmclreis 4:9 bsving elongated slots 43 which receive the ihreeded shanks of screws, extending outwardly from the end plates 16. Suitable thumb nuts are arranged on the screws which serve lo clamp the brackets. The slotsl l are of such length that the rollers will bell-loved from engagemeno'with the floor when the lower ends of the slots bear on lhc screws, therefore it will be evident that a partial vacuum within the casing may be varied by adjust ing the brnclcelasq Thus it will be seen that I have provided" a device which is exceedin ly simple in construcrion and comparative y inexpensive of manufacture, "embodying few parts and these so arranged that the danger of derangement will be reduced to a. minimum.

Having thus fully described the invention, what I claim as new ie:--

In a'porimble pneumatic cleaner, :1 sun tion creating device in con'rbinetion with an open bottomed casing 'interiorly divided into a plurality of vertlcel compartments, and provided atone end with a duel; tapering toward its ends with which duel} acid compertments communicate sand which communicates at its central part Willi said suction creating device, an agitator in each compartment, and means to actuate the suction creaiing device and sigitelcors.
